Dear Users
Our Commercial and Academic users around the world can use these same forums here as before i.e. the Altair Support Forum ,
Commercial users from India with solver queries can go to the Solver Forum for India Commercial Users ,
Academic Users from India and AOC India Participants are requested to go to the Forum for India Academic Users and AOC India Participants ,
We will be tending to all queries in all the forums promptly as before, thank you for your understanding.

Node coordinates: This specifies x y and z coordinate from global coordinate system.
Node Coordinate : This specifies x y and z coordinate from local coordinate system which you have created in your model using tracking system.

To get a projection of Displacement to a face normal create the following expression:
Dot(BCElemToNode(ElementAxisVector("0.0 0.0 1.0","LC0F1.Elements","LC0F1.Coordinates","Bisect"),"avg","LC0F1.Elements"),"Displacement")
For crash models:
Dot(BCElemToNode(ElementAxisVector("0.0 0.0 1.0","LC0F1.Elements","LC0F1.Coordinates","Bisect"),"avg","LC0F1.Elements"),("Coordinates"-"LC0F1.Coordinates"))
Make sure you use "Advanced" result math template when loading results.

Please refer attached fem for spring mass 1dof. You can export eigen value and eigen vector individually using HV query panel.
But if you want to consider the effect of modal analysis for Modal frf case then EIGVSAVE and EIGRETRIEVE option listed in subcase section would help you.
Check OptiStruct user guide for the detailed information.

I will check internally if it is possible to export eigen values of nodes along normal direction of their local surfaces in HyperView. I also want to know the end objective of this requirement.Please do let us know about same.

Please set animation mode to transient and change the legend to dynamic scale for plotting Dynamic analysis output in HyperView. This should vary result over the range of defined frequency.Refer attached screenshot.
